The composition of syngas is highly dependent on the type of material, gasifying medium, and temperature, which are always critical in terms of product yield and composition [29]. The most common materials for gasification are coal and biomass whereas, in the last two decades, other materials ...
Pressurized coal gasification is not only the key part of the Integrated Gasification Combined Cycle (IGCC) but also the better approach to increase the gasification reaction rate and capacity of the unit gasifier. In this work, the gasification characteristics for a sub-bituminous coal with an air...
Due to the availability of sludge resources, 458 of these urban CFPPs have been additionally retrofitted with sludge co-combustion system (SCs), namely roof photovoltaic-assisted power generation combined with sludge co-combustion for coal-fired power generation systems (PVSCs). Both of these ...
Gasification (or combustion) of coal/biomass char particles in an oxyfuel atmosphere 来自 sintef.se 喜欢 0 阅读量: 11 作者: Haugen Nils Erland Leinebø 摘要: Real space condensation is known to occur in stochastic models of mass transport in the regime in which the globally conserved mass ...
In the underground coal gasification (UCG) process, cavity growth with crack extension inside the coal seam is an important phenomenon that directly influences gasification efficiency. An efficient and environmentally friendly UCG system... Su,Faqiang,Nakanowataru,... 被引量: 20发表: 2013年 An Int...
Under the effects of environmental pollution, macro-economical conditions, markets downturn, and squeeze of clean energy, the operation condition of China's whole coal industry attracts more attentions in recent years. This study aims to investigate the comprehensive competitiveness of coal industry in ...
